Too w/wm it "um/y concern.-

Be it known that we, AUGUST OLsoN, a citizen of the United States, residing at Nineteenth and Buttonwood streets, Philadelphia, county of Philadelphia, and State of Pennsylvania, and'LoUrs W. (Eh FLYNT, a

subject of the King of Great Britain, residing at 876 Genesee street, Rochester, in the county of Monroe and State of New York, have inventedcertain new and useful Improvements in Shoe-Machines, of'which the following is a specification, reference being .had therein to the accompanying drawings.

This invention relates to shoe machinery, and has for its object the'provision of a machine possessing novel? characteristics rendering'the same practical and highly efficient for various usesnotably, in producingan imitation stitch or stitch-impression on the upper exposed surface or edge of the soles of boots or shoes or upon the Welt thereof.

' associated with said tool, preferably, though The invention comprehends the provision in a machine of the type above referred to of a'tool in combination with improved means for imparting thereto a differential forward and retrograde movement, also an angularly-adjustable support or table operatively not essentially, yieldably. mounted. v

The invention further embraces improved adjusting instrumentalities for the tool-actuating means and means whereby the .support or table may be'shifted away from the a tool to permit the insertion .of the work therebetween.

Theinvention still further comprehends means for successivel regulating the toolactuating means and t e shifting of'the table or support.

Among the novel features of a machine constituting a preferred embodiment of the thereof and operatively relate In the drawings, Figure 1 is a perspective view of the complete machine, Fig. 2is a vertical longitudinal sectional view, parts being shown in elevation and other portions broken away. Fig. 3 is a vertical transverse sectional view on the line as a: of Fig. 2. Fig. 4 is a view similar to Fig. 3 on the line y y of Fig. 2, looking in the direction of the arrow.

Fig. 5 is a plan view of the impression-tool and its immediately-associated parts. Fig.

6 isa vertical longitudinal sectional view on the line 2 z of Fig. 5; and Fig: 7 is a detail perspective view, parts being broken away,

of the iinpression-tool and its guard.

Referring now more specifically to the drawings, wherein like reference characters refer to' corresponding parts in the several views, A designates a frame, which in the main constitutes a hollow support for the operating mechanism .and serves also to inclose or house the same, said frame having a suitable base or column. Two rotatable shafts arranged irrparallel planes are supported one above the other in the frame A, the same being represented at B and C, respectively, and the former serving as the main drive-shaft and the latter the rotating shaft for an impression-formin'g tool D, the

scribed.

I details of which latter will be hereinafter de- The shaft B is adapted to be rotated by a at one end to any desired source of power. (Not shown.) The opposite or inner end of this shaft is fitted pulley E, arranged convenientlg with a crank b andcrank-pin b, the latter connecting,loosely with a saddle F, mounted to oscillate upon the shaft Cl The saddle just mentioned carries two pawls ff, pivotally supported upon cross-pins 'f spanning the space between the opposite members of the saddle, Fig. 2, and the pawls are disposed one at. each side of the vertical axis of av toothed ratchet-wheel G, keyed or other wise fastened to the shaft C. These pawls are constantly drawn inwardly toward each other under the tension of a spring g, which connects them, and when ot erwise unobstructed they engage the teeth of the ratchet G and through the medium thereof rotate the shaft C alternately in opposite d1- rections, one awl rotatin the shaft in one direction on t e downstro e of the pitlnan,

ice

.while the other rotates it in an opposite dibase or column of the frame A, bears upon rection on the upstroke thereof.

The differential or relative extents of movement of the pawls and the means for regulating the same may now be defined.

On the shaft C and free to revolve thereon are sleeved a pair of cams H, the same being provided with outwardly-extending arms h on opposite sides of the shaft, to which'are pivotedknuckles t j of treadle-rods I J. The

' lower ends of the treadle-rods are in'turn to a greater extent than the other.

pivoted to the treadle K at difierent distances from its pivot 7c, (clearly indicated at i 7".) Such being the arrangement, it is obvious that a movement of the treadle will revolve the'cams H around the shaft C, the one In practice one treadle-rod, I, is ,placed about twice the distance from the pit'ot 7c of the treadle as the other rod, J, so that one cam, the former, will receive approximately twice the movement of the other. The cams have raised portions h, (best seen in Fig. 4,) which when the cams are rotated under the free endskaf the pawls, said pawls having extended portions f for this purpose, will raise I them out of engagement with the teeth of the ratchet G, and thereby correspondingly limit orstop the rotation of the" shaft C, said raised portions being so positioned relative to the pawls that the one}, pawl engages a greater number of teeth than the other, the

resultant movement being a .differential' forward and retrograde rotation of the shaft C and tool B, the forward movement being always eater, whereby a progressive oscillation o the im ression device is maintained.

The treadle C is normally held-in itsg-rgtracted or uppermost position by mean ot-a s ring is, fastened at one end thereto and at t e opposite end to the base or column of the frame A, and when the treadle is in this posi tion the shaft C receives its greatest movethe cams H are rotated upon the shaft, and a less number of. teeth are engaged by the pawls in proportion to the movement of the cams, the forward movement being reduced ina greater proportion than the reverse movement, so that the work will continue to be evenl fed although the play of the pawls be great y reduced. For instance, if the machine be effecting an actuation of the impression-tool five teeth forward and three'teeth back when the treadle is in its uppermost po sition referred to then by simply depressing or adjusting said treadle the extent of actua-' tion may be readil regulated in the proportion of three teet forward and two teeth backward, it being understood thata full deipression of the treadle will shift the parts sufciently to stop the movement of the impression-wheel.

A screw S, threaded through a lugs on the the upper edge or surface of the treadle K, thereby limiting the upward movement of said treadle under the influence of the spring 7c, a lock-nut s retaining the screw in adjusted position.

The construction of the impression-tool, it being preferably in the nature of a knurlingwheel, will be clear from an inspection of the drawings. The same is of frusto-conical formation, its largest diameter being outermost and the periphery thereof being toothed throughout its extent. The inner end of the wheel is grooved or recessed, as at d, forthe reception of a lug or key d on the end of its shaft C, the parts being locked together by a screw D passing axially through the wheel D and into the end of its shaft.

Another feature of the invention is the provision of a brake for insuring against rotation of the shaftC when the pawls f f are disengaged from the teeth of the ratchetavheel G. This brake includes the following instru entalities: W represents a spring seated wit in the inner bearing W of the frame A for the shaft C and interposed between a washer w, directly abutting the inner end of said shaft, and a headed adjusting-screw w in line with the shaft. w is a collar fixed to the shaft C in any desired manner, conveniently by a key to, and w is a fiber or other washer arranged between said collar and the end of the outer bearing W of the frame A for the shaft C. The pressure applied by adjusting the screw w, transmitted through the spring W and washer w to the inner end of the shaft, thrusts the shaft outwardly in a longitudinal direction, and.thereby shifts the collar to to cause the fiber washer to to be impinged between the same and the end of the outer shaft-bearing, as before stated, whereby sufficient friction is created between the parts to adequately prevent rotation of theshaft C excepting when forcibly actuated by the pawls. The utilization of the spring W obviates the fine ad'ustment which would be necessary were t e screw w alone employed.

Operatively related to the impression-tool and conveniently therebeneath is a rotatable support or table L of substantially circular contour and beveled outwardly on its upper surface from its center to its periphery, as at Z. The table is arran ed at an angle to the axis of the shaft C, alt ough the former approximates a horizontal plane, the relation of the table-to the tool D being such that the ing from the bottom thereof and loosely fitting a recess m in a. carrier-block M, said block in turn being pivoted upon a horizontally-disposed pin m, passing therethrough and having bearings in separatedlugsorears N of a plunger to be now described.

The plunger 0 conforms generally to the interior of and is slidable within a cas projecting forwardly from the-frame A; A coiled spring P, confined within the lower part of the casin 0, yieldably supports the lunger, Fig. 2, t e upper end of said spring caring against an annular seat oat the 7 bottom of the plunger and receivinga' centergaging saidend at I gagement of the rod R V and in the frame A, this last-mentioned end being when in its normal ing stem or project on o /thereof, while the lower end of the spring seats upon a thimble p, which is adjustable throu h the medium of a screw 1), havin a thread ed engagement with the bottom of t adjustedposition by a nut 19 The plunger 0 is slotted at g to receive the end of a lever Q, which rests upon apin g inthe lunger bears at, its opposite end upon a ang-e a confined against lateral movement by vertical pins 0,. A tableshifting rod R is pivot-' e5 3 ed to the leverQ at a ends and depending therefrom passes freely point intermediate its througha vertically-disposed aperture '1' in the treadle K, an adjustable collar or nut en a point a predetermined distance beneath the under side of the treadle or raised position; he purpose of thenut r and the free-en with the treadle will e now pointed out.

When the treadle is first depressed, it will ,play over the-rod R until its under face strikes the nut T, when a continued downward move.

' ble is rotatably responding direction,

ment of said treadle draws said rod in a corthereby lowering the Q, and consequently lowersthe table L for outer end-of the lever through the plunger 0 the insertion and removal of the work to be operated upon. Owing to the distance or s ace between the under side of the treadle If and the nut 1 on the rod R suflicient free dom is afforded between the parts, whereby the initial manipulation of the treadle ulls the treadle-rods I and J to at first slow own and subsequently stop the operation of the impression-tool under the action of the cams and pawls hcreinabove referred to all prior to the bringing of the rod, R into action.

However, the adjustment is such that imme diately upon the stoppage of the impressiontool the treadle will abut the nut r and lower the table L, as aforesaid.

the angular position of the table L we emp 0y a headed screw bearing upon the, under surface of the free end of the carrier-block M; in 'which said ta gages a threaded recess t in the plunger 0,

isposed at an inclination approximating that of the axis of the pin 1. r

To prevent an undue elevation of the table ecasing 0 and locked in supported. The screw en Th under the action of the screw *and' spring P, some means is necessary to i 't the upward movement of the plunger, and to this end we provide a headed screw U, passing loosely through a perforated projection u, extendin rearwardly from the plunger O andalso t 'ough an. alined opening u in the frame A, the threaded end of the screw carrying a nut 11., adapted to contact the frame A surrounding the opening it, as is obvious.

Another'detail of importance resides in means for relieving the pivot-pin l of the table L of lateralor sidewise strain, said means comprising a roller V, loosely secured upon the reduced inner end 0) of the block M, whereby the roller is arranged adjacent to the periphery of the table and bears the under surface thereof directly beneath the impression-tool, this being the point of greatest operating pressure upon the table.

guard 14 (see Figs. 1 and 7) covers the outer or end face of theimpression-tool and serves to prevent the upper from being scratched or marred by being forced against T, plunger 0,

wheel. This guard is composed conveniently of a thin piece of sheet metal U-shaped in cross-section, to the ends of which are secured two ferrules 15 15; These ferrules en gage over two pins'16 16, which are secured in the frame A on o posite sides of and par allel with the shaft i The driving-pulley E is normally loose on the main shaft B and is provided with two bearing-bushes 2 2, preferably of brass or bronze metal, and a hardenedsteel bush 3, which is interposed between the bushes 2 2. The bushes 2 2 fit the shaft B, while the bush 3-is bored considerably larger. The rear end of the shaft is drilled longitudinally, as at 4, to receive a clutch-rod 5, and is also drilled laterally, as at 6, to receive a steel ball 7. In the samevertical plane with this ball are one or more holes 8 in the steel bush 3, these holes being somewhat smaller than the diameter of the ball. The inner end 5 of the clutch-rod 5 is substantially conical in shape,- and the steel ball rests on its periphery. This conical end of the clutch-rod is of such dimensions that when the ball rests on its smallest diameter the same does not come in contact with the bush 3 but when the rod is pulled out it forces the ball through the hole 6 in the shaftB and against the inner face of the bush 3 until it finds one of the holes in the bush, wheii it is forced partly in and is held between the bush and the shaft, and as the bushin is secured in the pulley the shaft is "grippe and must 'rotate with the pulley. e outer end of the rod 5 is shouldered at 9 to receive a knob 10, which is loose on the rod a'ndis held in position bya screw 11. This knob constitutes a' handle to operate the clutch-rod? against .or otherwise coming in contact with the p 12 is a collar secured to the shaft B by a screw 13 and serves to retain the pulley' against movement along the shaft.

A cover 17 is fitted to the top of the frame to complete the casing and protect the workin parts of the machine.

t is to be understood that numerous alterations and clian es may be made ire-the ma-' chine herein disc osed without in the least departing from the spirit ofthe invention;
